This document contains the basic control strategy, minimum functionality requirements, basic driver interface elements, minimum requirements for diagnostics and reaction to failure, and performance test procedures for Adaptive Cruise Control (ACC) systems.

ACC systems are realised as either Full Speed Range Adaptive Cruise Control (FSRA) systems or Limited Speed Range Adaptive Cruise Control (LSRA) systems. LSRA systems are further distinguished into two types, requiring manual or automatic clutch. Adaptive Cruise Control is fundamentally intended to provide longitudinal control of equipped vehicles while travelling on highways (roads where non-motorized vehicles and pedestrians are prohibited) under free-flowing and for FSRA-type systems also for congested traffic conditions. ACC can be augmented with other capabilities, such as forward obstacle warning. For FSRA-type systems the system will attempt to stop behind an already tracked vehicle within its limited deceleration capabilities and will be able to start again after the driver has input a request to the system to resume the journey from standstill. The system is not required to react to stationary or slow moving objects

The present document is composed of the following data packages:

— Indicators;

— Reusable components;

— Explicit frames for statistics

— Query. This document itself is composed of the following parts:

— main document representing the conceptual foundations and corresponding data model (normative);

— Annex A containing the data dictionary and attribute tables, i.e. the list of all the concepts presented in the main document together with their definitions (normative);

— Annex B presenting the model evolution (informative);

— Annex C, providing details of the significant technical changes between this document and EN 12896-8:2019 (informative) 

This document specifies interoperable application profiles for the information exchange between toll chargers (TCs) and toll service providers (TSPs), by selecting suitable options from the base standard EN ISO 12855:2025.

This document covers: 

— exchange of information between back-end systems of TCs and TSPs, e.g.: 

— charging related data (toll declarations, billing details, payment claims, payment 

announcements); 

— administrative data (trust objects, EFC context data, contact details for enforcement, etc.); 

— user related data (exception lists, user details, abnormal behaviour information, CCC 

event data, user complaints); 

— confirmation data. 

— transfer mechanisms and supporting functions; 

— semantics of data elements;

— definitions (Annex A) of restrictions on data types w.r.t. the ASN.1 definitions in the base 

standard EN ISO 12855:2025 by introducing an XML Schema Definition (XSD) for each specified 

profile; 

— implementation conformance statement (ICS) proforma (Annex B), as a basis for evaluation of 

implementation for conformity to this document; 

— an interoperability statement proforma (Annex C), as a basis for assessment of transactional 

interoperability between the technical implementation of a TC and a TSP; 

— a web service definition (Annex D) covering the use of simple object access protocol (SOAP) 

services as communication technology. 

The implementation of the underlying back-end systems and their business processes is not covered. 

Therefore, the following aspects are outside the scope of this document: 

— details about how back-end systems use the authenticator data elements of the base standard to 

implement security; 

— how to use the data exchange to operate compliance checking and the enforcement process; 

— commercial aspects; 

— definition of non-functional features such as key performance indicators, acceptable fault levels, 

availability of interfaces of TC and TSP, and reporting requirements. 

This document further explains the correspondence between the European electronic toll service (EETS) 

legislation and this document (Annex E).
